Our model parameters are listed in Table REF . In LFHQCD, \(\kappa \) , the strength of the holographic confining potential, is obtained from the \(\rho \) -\(\pi \)  mass splitting for the light vector sector, viz \(M_\rho ^2 - M_\pi ^2 = 2\kappa ^2\) ,
and \(M_{K*}^2 - M_K^2 = 2\kappa ^2\) , while for the light pseudoscalar sector, \(\kappa \)  is obtained from fitting to the Regge slopes [1]}.
Note that the values of \(\kappa \)  obtained from the \(q\bar{q}\)  and \(s\bar{q}\)  sectors coincide, indicating the universality of the holographic confinement.
Since the determination of \(\kappa \)  does not involve the longitudinal d.o.f., we adopt the same values for \(\kappa \)  in this work.
